The plants grow in pine woods at Leland Stanford University,. 
California. The habit, size and shape of the stem are very 
similar and the spore measurements exactly the same as in our 
plants hut the colors are darker. 
3. Medium sized plants with a membranous annulus. Type 
of Pholiota praecox and Pholiota dura. 
Pholiota praecox, (Pers.). Pis. XXYII and XXVIII, A, B. 
EARLY PHOLIOTA. 
The early Pholiota is quite common on manured lawns and 
in grassy places during the spring and summer. The plants 
photographed were collected near Chicago in June. 
Pileus smooth, white with more or less yellowish or tan 
color, especially in the center, usually convex but sometimes 
umbonate. Lamellae broadly sinuate adnexed, slightly ventri- 
cose, whitish becoming rusty or fuscous brown. Stem white, 
smooth, more or less striate, even or slightly tapering downward, 
straight or flexuous. Annulus thin, membranous, separating 
from the pileus or from the stem. Spores rusty 6—8x10—12 y. 
The species is variable, Peck reports: 
Var. sylvestris. Pileus with a brown center. Growing in 
woods. Var. minor. Small, with the veil separating from the 
stem and remaining as an appendiculate margin on the pileus. 
Pholiota vermiflua, Pk. PL XXVIII, C—F. 
WORMY PHOLIOTA. 
The species is described in X. Y. State Mus. Kep’t 31, p. 34 
and figured in Mus. Bull. 75, pi. 86. It is closely related to 
Pholiota praecox but somewhat larger, cap whiter, often cracking 
into areas, stem striate above the annulus, lamellae darker 
brown and spores slightly larger. Its habitat is the same as 
that of Pholiota praecox but it occurs later in the season. Our 
plants were collected in the mulching by a fruit tree late in Sep¬ 
tember. The cap was almost white and the lamellae darker 
brown than in Pholiota praecox. The spores were 8x12—13 /*.
